Dell VNX5800 VNX Series: Introduction to SMB 3.0 Support - Page 23

Large IO The SMB 3.0 protocol, by default, enables large IO sizes for reads and writes. The maximum I/O size is now 1 MB, which improves performance for large data copies by limiting the number of SMB commands on the network. Conclusion Data availability, performance, and security are factors that you must consider in your organization's IT infrastructure. This is especially important when organizations have remote offices across different regions of the world. You can utilize the VNX support of the SMB 3.0 protocol, along with Microsoft Windows 8 and Windows Server 2012, to address some common concerns. Continuous Availability and Multichannel are features that maintain data availability in a failure at the client, server, or network level. Offload Copy enables efficient data consolidation or migration of content stored on CIFS shares. BranchCache V2 optimizes the local link utilization and the responsiveness of applications, and reduces the WAN bandwidth consumption. In terms of security, SMB Encryption enforces protection when data is exchanged between Windows clients and VNX over untrusted networks, and enables administrators to decide which Windows clients are granted access to this data. Leveraging RVSS, point-in-time snapshots of the CIFS shares can be taken across multiple shares and provide improved performance for backup and restore.
